Mastering Bulb Gardening: Selection, Planting, and Care for Gladiolus and Daylilies

Why Choose Bulbs?

Bulb plants offer numerous advantages: they are generally inexpensive, durable out of the ground, and hardy once planted. Shopping for bulbs is straightforward—select firm, healthy-looking bulbs and avoid any that are cracked, dry, or soft.

With so many types available, choosing the right bulbs can be challenging. This guide covers two popular choices—gladiolus and daylilies (Hemerocallis)—with detailed planting and care instructions.

Gladiolus: Dramatic Summer Spikes

Characteristics

Gladiolas are instantly recognizable by their sword-shaped leaves and funnel-shaped flowers. Their large size (3–6 feet tall) and wide color range make them excellent centerpieces.

Planting & Care

When: Plant in spring after soil has warmed.
Bloom time: 65–100 days after planting. For continuous blooms, plant new bulbs at 1–2 week intervals over 4–6 weeks.
Depth: Plant four times as deep as the bulb is wide (e.g., a 1-inch bulb goes 4 inches deep).
Spacing: 4–6 inches apart.
Light: Full sun.
Water: Regular watering during growth and bloom.
Winter care: In many regions, bulbs can stay in the ground. If lifting, dig after leaves yellow, dry 2–3 weeks in a single layer, then store in nylon stockings or onion sacks in a cool, well-ventilated place.

Hemerocallis (Daylily): Hardy, Trouble-Free Beauty

Characteristics

Daylilies form arching, sword-shaped leaves and produce flowers 3–8 inches wide in a vast color palette. Hybrids can reach 6 feet tall. Each bloom lasts only a day, but successive buds open daily, extending the show through spring and summer.
